True ka dyan Alistair, at least nabawasan na yung wires from the the AVR to the speakers, worry ka na lang kung saang power plug/point mo ikakabit. Anyway if they can wireless RF why can't they do it in V/A? Tanong lang.
-P-A-
Ever wondered by wireless headphones, even coming for great headphone makers like Sennheiser, are not widely accepted among seasoned audiophiles?
There have been experiments and prototypes in this direction for amps and speakers The problem is fidelity. Any kind of wireless transmission requires a carrier medium to "carry" the audio signals. Unfortunately, any technology employed reduces much of the fidelity, reducing the bandwidth and introducing some noise at the points of transmission and reception. Perhaps a concerted research should eliminate these but the industry finds no incentive as the market is really lukewarm to the idea to say the least.
Another limiting concern is the power. Bear in mind that amplifers output large high current high voltage signals to drive the speakers. Carrying them over a short distance will require high wattage transmission that may not be feasible in the home. A solution to this is to couple the power amps to each speakers directly, sort of like your powered subwoofers. That means every speaker you use would have to have its own power amp and an antenna receiver. So that the transmitter at the end of the preamp will just transmit small current signals from a preamp to the power amp receiver. That's more feasible.
But that means a total overhaul of your set-up. Apart from getting separate powered speakers PER channel, you need a multichannel preamp. Then if there are wireless products out there that carry the preamp's discrete 5.1 signals either as optical, radio or infrared and a matching receiver connected to each speaker, then you can have a wireless connection. Ofcourse you could start with a set already consisting of powered speakers and preamp with built-in wireless transmission and reception capabilities. Whichever, you'd have to thrash your current gears. Or modify them.
